COMPOSITION.

No Drawing.

To all whom it may concern:

Be it known that I, Ovm P. BARBOUR, a citizen of the United States of America, and resident of Winfield, in the county of Cowley and State of Kansas, have invented certain new and useful Improvements in Compositions, of which the following is a specification.

This invention relates to metal polish, and

articularly to a composition for polishmg articles and containers made from aluminum.

An object of this invention is to provide a plastic composition to be applied to the surface of articles formedof aluminum for the purpose of removing discolorations and darkened deposits which may have formed thereon.

I have found that the composition hereinafter set forth contains ingredients which meet chemically with components of the discolored surface and thereby acts as a solvent on the deposits, rendering the surface of the aluminum clean and bright.

In the preparation of my polishing composition, I employ oxide of aluminum, sometimes known as aluminum concentrates, sulphate of aluminum and tartaric acid, preferably in the following proportions, viz:

Oxide of aluminum 2 parts; Sulphate of aluminum 1 part; Tartaric acid. 2 parts although the proportions may be variedslightly, but not to exceed 5%.

In the use of the composition, it is preferably applied with a dampened cloth or' Application filed November 25, 122. Serial No. 603,354.

tinued action, a brilliantly polished surface results. The polished surface is then wiped to remove the adhering cleaning agent, and polished with a dry cloth, and while this is probably the preferred method of use of the composition, a small quantity of the composition, together with boiling watermay be placed in the vessel itself or in a container in which the article to be cleaned is immersed, and allowed to boil for a few minutes. This method lessens the labor of polishing somewhat and may be found desirable in some instances.

The composition has proven effective also if placed in a container with hot or cold water in which the article to be cleansed is immersed, and allowed to remain several hours, the amount of composition to be added depending, of course, upon the amount of water placed in the container. I have found in these latter .two methods that a teaspoonful and a halfof the composition to a quart of water is usually suflicient.

I claim:

1. The herein described composition of matter for cleansing aluminum articles, comprising oxide of aluminum, sulphate of aluminum and tartaric acid, adapted with the addition of water to remove deposits and stains with which it is placed in contact.

2. The herein described composition of matter for cleansing aluminum articles, comprising Oxide of aluminum 2 parts; Sulphate of aluminum--- 1 part; and Tartaric acid 2 parts adapted with the addition of water to remove deposits and stains with which it is placed in contact.
